A hint of what information is needed comes from recalling that dynamical systems are models and as such, they leave aside a multitude of degrees of freedom—deemed irrelevant to the model, but nonetheless coupled to the “system”. A useful framework to deal with them is the one set forward by Langevin [1]}, which makes the dynamical flow into a stochastic process (thus nonautonomous, albeit driven by a stationary “white noise” process).
